To whom it may concern:

Beit' known that I, EDWARD A. Hammers,

I aratus by means of which an internal-com ustion env,gi'nemay be started without the usual crankmg operation, and it is adapted particularly for use upon motor-vehicles, though applicable to engines used in other connections. w v

The invention relates particularly to devices, of the kind above referred toyof the type in which the engine is started by forcing a combustible mixture of air and vaporized gasolene, or other fuel, into one or more of the cylinders of the engine under pressure, and then igniting the mixture so introduced.

The object of the invention, broadly stated, is to produce apparatus of this kind which shall he sim le 1n construction and operation, the com ustihle mixture being produced by a manually-operable dev ice comprising an air-pump and a fuel-measuring device.

A feature of the invention resides in the arm gement of the air-pump and the fuelrne lring device, bywhich a slngle manwill --operable member is employed to operate oth of these parts by movements in difl'e'rent directions. 7

. Another feature of the invention resides in certain improvements in the construction of the automatic distributin device by which the combustible mixture is directed to those cylinders of the engine in which the pistons and the valve mechanism are 1n proper position-to produce the starting 1 mpulses, and in this respect the present 1nvention is an improvement upon the invention disclosed in my pending application Serial No. 580,785, filed September 6, 1910. In the drawings: Figure 1 is a side elevation of an apparatus embodying the present invention, as employed in connection with a foiir-cylinder engine; Fig. 2 is a vertical section of the air-pump and the fuel-measnrm'g and vaporizing devices;' Fig. 3 is a plan-view of the parts illustrated in Fig. 2, taken partly in section on the'hne 3-3 m Specification of Letters Patent. Application filed December 16, mo.- ser'iax N0. 597,732.

-' ELEC- the latter figure; Fig. 4 is a right-hand side-elevation of the distributer, shown partly in section on the line 44 in Fig. 5; and Fig. 5 is a vertical section. on the line 5-5 in Fig. 4, looking from left to right in the latter figure.

The illustrated embodiment of the invention comprises, as shown in Fig. 1, an air pum indicated generally by the reference num er 6, which is operated by means of a handle 7. At the base of the air-pump the air is admitted through a check-valve 8, while liquid fuel is admitted through a pipe 9 connected with a fuel-tank 10. The fuel and air are mixed in a chamber at the base of the pump, andare then forced under ressure, through a pipe 11, to the distri uter 12. From the latter the mixture is conducted, by pipes 13, 14 15 and 16, to the respective cylinders 17 oi the engine. As shown in Fig. 1, the mixture is introduced through valve-bodies 18 which embody also the usual priming-valves.

The construction of the air-pump and the fuel-measuring device is illustrated particularly in Figs. 2 and 3. The pump has a cylinder 21 which is screwed into a cap 22. The cap has depending legs integral with a ring 23, by which the pump may be socured in place in an opening in the floor of a motor-vehicle, or Wherever the device is to be used. Within the pump-cylinder is a plunger 24 which slides through the cap 22 and carries the handle 7 fixed at its upper end. The pump-piston comprises a disk 25 at the lower end of the plunger, and two oppositely-arranged cup-leathers 26. The cup-leathers are held against the piston by a disk 27 provided with a threaded stem 28 screwed into the lower end of the plun er.

The lower end of the pump-cylinder is closed by a. casin 29 which is provided with Beneath this para horizontal partition 30. tition are two chambers 31 and 32 which are separated by a rotary'valve-member 33 of generally-conical form. The chamber 31 is supplied with liquid fuel through the pipe 9, and the valve-member 33 is provided with two lateral recesses, 34, either of which: is adapted to communicate with the chambers 31 and 32. The valve-member is provided with a squared projection 35 at its upper end, which is adapted to 006 crate with a squared recess 36 in the disk 2 at the lower end of the plunger. These latter parts are Metastas s 1911.

normally kept out of engagement by means of a s ring 37 coiled about the upper end of imparting a half-rotation to the valve-member 33. By this movement the one of the recesses 34 which is, at the time, in communication with the fuel chamber 31, and is full of fuel, is brought into communication with the mixin chamber 32 and discharges its contents therein. To provide for arresting the measuring-valve at the end of the half-rotation, the valve has a downwardly-projecting squared stem 38 upon which is mounted a washer 39 having upward projections 41 adapted to engage corresponding recesses in the bottom of the casing 29. This washer is pressed upward into engagement with the casing by aspring 42. This spring serves also to maintain the valve-member firmly against its seat in the casing.

After the fuel has been measured as above described and delivered to the mixing-chamber 32, the handle 7 is raised to draw air into the mixing-chamber and the pump-cylinder. The air enters throu h an opening 43 in the casing of the chec -valve 8 and passes into the mixing-chamber 32 through a nipple 44 connecting the check-valve with the casing 29. From the mixing-chamber the air passes through a passage 46 in the partition 30, and thus into the pump-cylunder. The handle 7 is then depressed, thus compressing the air and forcing it from the pump-cylinder through the mixing-chamber and the casing of the check-valve. By its passage through the mixing-chamber the fuel is vaporized and mixed with the air, and the air is prevented from escaping through the inlet 43 by means of a pivote valve-member 45 in the checkvalve casing. The mixture of air and vapor passes u wardly through a spring-pressed chec valve 47 of ordinaryilform, and thus into the pipe 11, through w ich it is transmitted to the distributor 12, as shown in Fig. 1. The strokes of the air-pump are separated until the necessary amount of air has been introduced into the engine-cylinders, and the engine may then be started by a suitable operation of the ignition-devices.

The casing 29 is provided with four downwardly-projecting lugs 49 having threaded openin s which are adapted to receive the ends 0 brace-rods, or other fastening devices, when necessary to steady the pump upon the vehicle in connection withwhich it is used. r

The arrangement of the air-pump and the fuel-measuring andmixing devices, as just described, produces a compact and simple constructron in which a single manually operable member is employed in the performance of all the functions of the device. A valuable feature of the form and arrangement of the fuel-valve 33 resides in the fact that while this device, when rotated, permits the necessary amount of fuel to pass into the mixin -chamber, there is no position of the va ve-member in which a free passage is aiforded for the fuel, and consequently danger of escape of fuel, owing to careless operation of the device, is entirely eliminated.

The construction of the distributer 12 is shown particularly in Figs. 4 and 5. This device has a casing which 1s centrally drilled to provide an inlet 50, which is connected with the pipe 11 as shown in Fig. 1. From the inlet 50 two horizontal passages 51 lead to two similar vertical passages 52, each of which is closed, at the upper end, by a screw-plug 53. \Vithin each passage 52 is screwed a valve-seat ring 54 cooperating with a check-valve in the form of a ball 55 pressed upwardly by a' s ring 56. Each valve-seat ring 1s notche to receive the lower end of a coiled spring 57, of which the upper end is seated in a notch in the corresponding plug 53, and this arrangement prevents the valve-seat ring from rotating out of adjusted position.

The combustible mixture, after passing through the passage 52, emerges at the r 100 lower end, through an opening 58, into a hardened steel sleeve 59 in which a hardened steel valve-ball 61 moves horizontally. This ball cotiperates with seats at either end of the sleeve formed in plugs 62 and 63 screwed into the casing of the distributor. These plugs are perforated, and are connected with the pipes 13, 14, 15 and 16 by which the combustible mixture is commumcated to the engine-cylinders.

' The valve-ball 61 is maintained normally in engagement with one or the other of its seats by means of a detent in the form of a hardened steel ball 64 which is pressed upwardly, by means of a spring 65, into engagement with the valve-ball. When the latter moves from one. end to the other of the sleeve '59 the detent-ball is momentarily depressed, but springs upwardly again into engagement with the rear of the valve-ball, as shown in Fig. 5, thereby preventing accidental movements of the latter.

The operation of the distributer just described 15, in general, the same as that described in my copending application hereinbefore referred to. Dunn the normal operation of the engine, at eac compression stroke of the piston in one of the enginecylinders, the pressure of the gases in the cylinder is communicated, through one of the pipes 13, 14, 15 or 16, to the correspondpipe in questioiigso' that in whatever p'osition the engine may comeyto rest when its operation is' discontinued the valve-balls 61 in the distributer are left in such position that when the starting apparatus is thrown into operation the combustible mixture may be'forced into the cylinders in which the pistons are on the com ression or the ex ansion strokes, and w en these c linders have been so charged with combusti le mixture it is obvious that, b throwing the igniting devices into operation in these cylinders, one or more impulses may be produced sufiicient to initiate the normal operation of the engine.
